IMPROVED PBNSTOCK FOR UNDERGROUND DRAINS.

TO ALL WHOM I T MAY'CONCERN: I

Be it known` that I, DAVID A. PARKS, of Fairviemin the County of Fulton, and in the State of-.Illinois,

- have invented.A an Improved Penstock for Underground Drains; and I do hereby declare that the following is a full and exact deseription thereof, refercnoe being had to the ac'eompanying drawings, and to the lettersof refer# @noe marked thereon, making a part of this speuiiication, in which- Figure l'isa sectional elevation, taken through iig. 3 on the line R R.

Figure 2, a sectional elevation, taken through the line X X, iig. 3.

Figure 3, a. horizontal section, taken on the line Z Z, figsJ 1 and 2.

The nature of' my invention consists in attaehing short pipes to the opposite sides of the penstopk, for extending into 'the openings of the mole-drain, and dividing the penstook with a partition of -less height than the sides, whereby Water may rise high enough for stock to drink, and yet. allow the surplus'to passidown at the opposite side of the partition, and through'the drain; yand further, in arranging a gate to slide onthe partition, for the purpose of shutting wateren or oli', as the oase may require.

To enable others to make and use myinventon, I have marked corresponding parts withI similari'etters,

I. and vvill now give a detailed description.

i A. A represent u box penstook, with a bottom, o, and lid, H, made oi' plankmatohed together watertight, un'd of such a. heightas will bring the top of the stock a little above the ground; when set for use, Y B B represent two pipes, ommunicatin'g -with the stock A A, near its bottom, S, and are used to form so much of the mole-drain, atv opposite sides oi' the stock, as' is neessnryto make a perfect water-connection, and to prevent the `earth from entering the drain whemthe stock is boing paoked in' theground. This arrangement 'I onsider --n'ot only new, but important, for without the pipes, or a. similar device, a sixitable'dater-eonnection cannot bemade for the kind of drains referred to. t

D represents ,a partition, arranged inside of the stock A A, for the purpose of retaining water in the larger apartment, for farm purposes, and permitting the surplus to run over the top of the partition, and into the drain, ut theopposite side Vfrom where it enters. The partition has an opening, G, `n'ado as largo as or larger than the pipes B B, anda. gate, E, for the purpose of permitting the Water to run directly through the stock, and oarry oil' thesedimentjv-hich might accumulato in the bottom of the same. l

'In order to set the penstock for use, theeurth should be removed to a. point a little below thebottom of the moie-dr'ain, as shown at fig. 1, after which the pipes B should be fittedA carefully? in the water-course, and covered with short'. pieces' of plank, as seen at'J J, saine figure. The earth should then bo' packed closely against-the penstock, so as to provcnt'wutor from rising around it, and the stool: is'then'rcad'y for use.

Having'thus-deseribed my invention, I do not claim a peustoclionelevating water, 'but What I-do claim, and desire'to secure by Letters -Pat'ent of, the United States; iss- The ombination of the vstock A A, partition D, gate E, and pipesY I?, arranged substantially as and for the purponherein deaeribed.

` DAVLDA. PARKS.
